Sorry guys I'm sure this topic has been done to death in here.
I currently have one nest thermostat and i have another on the way
In the meantime i've been quoted £175 to get both Zones setup by a Nest Pro, with that in mind I decided to take a look at it myself before commiting
The boiler is a Potterton Promax Combi HE Plus
Having read mulitple posts from others with similar setups i've managed to setup the first Heatlink by replacing the programmer, this was straight forward, and with the current setup i can run the house as a simple single zone setup by moving the two Brown (Ground Floor) and Black (1st Floor) wires that were on Programmer's Terminal 4 Normally Open to the Heatlinks Terminal 3.
In the old thermostat boxes I joined the Brown and Black wires together so each old thermostat is essentially always calling for heat and safely terminated the Neutral wire as it was now redundant (i think?!) These wires were also only supplying 5v so i couldnt use this to power the Nest Thermostat as the internal battery kept on dying so at the moment the Nest thermostat is powered by USB.
Is this the correct way to go so far?
When the second Nest arrives, i guess i would need to wire that one up directly into the wiring centre to completely make the upstairs wiring to the old thermostat redundant? This is were my head is a little scrambled on how that would be accomplished.
Ideally, i would want to move both heatlinks to the cupboard with wiring center but its not a problem to leave the downstairs heatlink were the old programmer was, so really at the moment I just need a little direction on how I would add the second heatlink.
Oh and is there anyway to get 12v delivered into the old thermostat outlets so I could mount the nest thermostats on the walls?
Thanks in advance!
